90%) in about 2.5 hours. A 5600 mAh pack will take approximately 3.5 - 4 hours to charge. Since a
depleted battery pack absorbs charge current faster, than a partially charged one, most of the charge
energy is absorbed during the initial stage of charging and then the rate of charge levels off towards
the end.
Charge channels
Both charge channels are fully independent from each other; charge initiation and termination
depend on a battery’s state of charge. An LCD display indicates each battery’s state of charge, in
voltage, percent of readiness (estimated), and amount of charge in mAh input in it since the battery
insertion.
Test/Discharge circuit (optional)
With the Test/Discharge circuit installed, the charger becomes a complete battery management
system enabling battery characterization, as well as identifying anomalies resulting from aging and
other deficiencies.
The test performed is a full charge-discharge-full charge routine. This test will identify the true
capacity of the battery displayed on the LCD panel. The discharge circuit closely approximates actual
real life discharge, as seen by the battery in normal camera use.
The circuit is associated with channel 1.
Operation
Charging
Operation of the charger is fully automatic. Mount any battery to any open position on the charger
and the charger will initiate the charge routine. While charging is in progress, the LCD display will
indicate the battery voltage, estimated readiness in percent, and amount of charge accepted by the
battery. Upon charge completion, the display will report the position number (1-2), amount of charge
the battery has absorbed, and the completion message.
Upon the battery insertion, the charger will identify the battery’s state of charge, and initiates the
appropriate charge regimen. If the inserted battery is fully charged, it cannot safely absorb charge.
The charger will display the “ # 1(2) Ready” message.
Note:
 Estimated readiness is intended for the “charge in progress” status information. Accuracy may vary for an old
or new battery, and between different sizes and makes.
 Amount of charge absorbed by the battery is displayed from the moment of insertion. If a fully depleted
battery charged in full, the charge displayed is equal to the actual battery capacity in mAh.
 Upon the battery removal, please wait 2-3 seconds before inserting a new battery in the same position, as the
charger channel needs this time to initialize.
Status LEDs
LEDs help to quickly identify charging state.
1. Fast blink
Battery is inserted; charge in progress
2. On Battery is ready (charged over 90%)
3. Slow blink Test in progress
Testing (optional feature)
 Insert the battery to be tested in position 1.
 Press “Test” button
